3 EPA Ecoregions
For some geological classification that isn’t based on watershed boundaries, we turn to the EPA’s Ecoregions.
Intent here is to list which ecoregions are in our watershed, and which are in each basin (using MDEQ’s divisions). And maybe how much are of each basin belongs to each ecoregion. Plus show a map.

The Mississippi Sound Watershed contains 4 level-3 ecoregions:
- 65 Southeastern Plains
- 73 Mississippi Alluvial Plain (in the very southwest corner)
- 74 Mississippi Valley Loess Plains
